Having the right amount of insulation in your attic can make your Nashville home more pleasant throughout the seasons. Better energy efficiency could also help you save money on heating and cooling costs.
You can measure existing insulation to determine if you have enough in your attic. If it’s less than 7” deep, your Nashville home lacks enough insulation. Depending on where you live, between 13-14″ of insulation to as much as as 16-18″ of insulation will be what’s recommended. In addition, if your home is older than 10 years, you’ll probably need more attic insulation in your Nashville home.
Enhancing your insulation levels could positively impact your energy bills, saving you up to 20 percent.** It can provide a vapor barrier against humidity, stop air leaks, and may limit wear and tear on your HVAC system.
**Savings may vary.
There are three kinds of attic insulation—spray foam, loose fill and batt.
Spray foam insulation mixes liquids that harden into a foam on contact. Closed- or open-cell applications can be used in attics.
Closed-cell foam provides the most insulation. It also creates a comprehensive barrier against air, vapor and water.
Open-cell foam expands when applied, plugging cracks and other spaces that are hard to get to. It’s best for blocking air but isn’t completely waterproof.
Both types of spray foam insulation may even help absorb noise.
Loose fill insulation is put in place using specialized machinery, while batt insulation is rolls that can be cut to fit. Insulating material can contain fiberglass, cellulose, mineral wool and cotton.
Insulation is rated for its resistance to heat flow. This is also called the R-value. Certain levels are suggested based on where you live.
